Specification of Letters Patent.

Patented July 22, 1913.

Application filed May 20, 1912. Serial No. 698,415.

To all whom it may concern:

Be it known that l, dorm .l. :hNG'US, a citizen of the United. States, residing at hand aven, in tl .e county of Ottawa and State of ii'lichigai'i, have invented a new and useful Vise, of which the following is a specification.

lily invention relates to imyn'ovements in quick acting rises in which the movable m jaw may be quickly pushed or drawn to the required. position before tightening upon the object to be held.

The object of my invention is to secure speedy, simple and convenient operation;

uniform and proper distribution of stress, and perfect unvarying alineinent of parts at any and all. positions when in operation, combined with strength, rigidity and grace ful proportion in construction. I attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1, is a side view of the assembled vise complete with a portion of the side removed to reveal the positions of the working parts while the vise is being used. 2, is the same, showing the movable jaw tilted, in which position it may readily be drawn open or pushed. into contact with any object to be held. lTig. is a sectional view on the lin ih l1. Fig. l, a view of the movable jaw and supporting ribs and showing the screw in section, and Fig. 5, a section of ll ig. 4t on the line C D, showing the corn struotion, by means of the vertical and horizontal ribs, the latter being shown with arched rib attacl'ied, covering the shaft.

iiiimilar numerals refer to similar parts throughout the several views.

in Fig. 1 and 2, l is a hollow box or arch forn'iing the body, shown resting upon the base plate 3 and bearing the fixed jaw of the vise. Extending the length of the top of said hollow body and within same is a fixed screw rack 5 with teeth to engage the threads of the screw 4;. At the sides within said hollow body and extendiiig in front of same are stationary tracks 14 and 16.

The traveling or sliding part of the vise 2 carrying the movable aw is plainly shown in operation in Figs. 1 and 2. Fig. 4t shows this movable part and its manner of adjustment to the screw shaft and screw. Fig. 5 shows the construction being a ribbed eX- tension above bearing shoes (3 and 9, at the sides underneath, and the deep vertical rib 11 extending to the rear and supporting the screw 4-.

Fig. 3 shows the cleft rib 13 in its use as guide to the movable part 2 by means of contact with the rib 11. in Figs. 1 and 2 a similar rib 12 is shown in dotted lines. This also acts as a guide in the same manner as and in conjunction with the rib 13.

The sectional view of the screw -i; in Fig. st shows the manner of attaching said screw to the shaft 7. The screw being cored out or bored to more loosely upon the shaft and slots 1? cored or cut on the opposite sides of the hole for about one-half its length to receive the projecting ends of a pin. in the shaft In the illustrations the screw t is shown with circuinfercntial ratchet threads and the rack 5 having teeth formed of threads corresponding to the threads f the screw, thus forming a longitudinal section of a nut for said screw.

In o 'ieration the movable or trz'iveling part 2 rests entirely upon the shoes or bearers 6 and 9, said shoes acting as a fulcrum. The front portion being heavier than the screw end of part 2 forces the screw st up into contact with the rack engaging the threads. vVhen by means of the handle 8 and the shaft 7 the screw is turned to operate the vise, the screw is forced against the rack with increasing pressure as the object held is pressed. more firmly between the jaws. i hen the screw is loosened suliciently to release the object held, the movable jaw may be raised tilting upon shoes or bearers (1 and 9 when it may be pushed or drawn to any position required, the shoes sliding upon the tracks 14: and 16.

My arrangi-mient and COlnlJll'ltttlOll of parts permit of any degree of strength in any and all places that may be required. T here are no small parts requiring manipulation or adjustment before using the vise in any of its movements. The screw shaft is relieved of any side pressure which might cause it to bend or spring causing the threads of the screw to slip on the rack.

The form of construction provides a convenient anvil face on the top of the vise.

Having thus described my invention, what I claim and wish to secure by Letters Patent, is:

1. In a vise, a fixed hollow body with rack located in the top of the inner cavity extending from front to rear end, stationary tracks attached to the sides of said hollow body within, extending in front parallel to the direction of said rack; a traveling tiltable part bearing the movable jaw of the vise at one end and a screw attached to a shaft at or near the opposite end and provided with shoes or bearers upon which said traveling part rests, slides and tilts upon the tracks in the fixed vise body, as shown.

2. In a vise cut and in combination with the stationary body portion providing a supporting guide therefor, a sliding or traveling part carrying the movable jaw of the vise at one end and a screw operated by a shaft at or near the other end; said traveling part being provided with a rounded or projecting portion or portions underneath and between the said jaw and screw, said rounded or projecting portion or portions forming a rest, shoes or bearers upon which the said traveling or sliding vise part tilts bears and moves in the vise body for the purposes herein set forth.

3. The combination in a vise of a stationary aw having in it a longitudinal way or passage, and a rack formed in the top of said passage from front to rear thereof, a movable j aw having a tiltable supporting arm extending into said passage; an operating sh aft mounted in or upon and extending rearwardly along said arm and a screw mounted on and operated by said shaft and thrown into or out of engagement with said rack by the tilting of said arm.
